Leesa Evans, the woman referenced in the Instagram post, is a costume designer who often dresses Amy for big events.

Amy also shared a second image, this one shows her goofing around with her husband, Chris Fischer.

Fans immediately began congratulating her, seeing her post as a pregnancy confirmation.

"OMG, your girl is pregnant!," one person said. Others told her that she's going to be a great mom. Some weren't so quick to jump onto the pregnancy train. "This post is misleadingly confusing," one person said. Another speculated that she and Leesa were starting a clothing line for plus-size women.

About an hour of speculation, Amy posted a video to reveal that she is not pregnant.

"I am not pregnant, I am not pregnant. I'm sorry, my hands, my friends said my hands were near, it looked like I was pointing to a bump or something, but I am not," she said. "Leesa and I have created a clothing line and for all sizes and shapes and, um, at a chill price point. Um, that's what I was trying to allude to but thank you for thinking of my womb."

The actress and her husband of five months have been in Spain vacationing with Jerry Seinfeld, Jessica Seinfeld and comedian Colin Quinn. In an image posted with Colin, she appears to be drinking sparkling water.
